Abstract

Twenty bis (fluoroalkyl) alkylphosphonates of structure (RFO) 2P (O) R were prepared in 28– 69% yields by treatment of alkylphosphonic dichlorides Cl2P (O) R [R= Me, Et, n-Pr, i-Pr] with fluoroalcohols RFOH [RF= CF3CH2, H (CF2) 2CH2, C2F5CH2, C3H7CH2,(CF3) 2CH] in diethyl ether in the presence of triethylamine. Reactions of isopropylphosphonic dichloride with two molar equivalents of alcohols and fluoroalcohols were compared. After ...
